Summary: This article presents a method to enhance the moisture resistance of fragile metal-organic frameworks (MOFs) by constructing a customized hydrophobic porous shell, NTU-COF, on MOF-5 using the Plug-Socket Anchoring strategy. It was found that the pore structure of MOF-5 was well preserved and could achieve complete CO2/N-2 separation even under humid conditions. Atomic resolution inspection of the interface between MOF-5 and NTU-COF revealed insights into the assembly mechanism of the core-shell structure.

Summary: In this study, a functional phase-pure interpenetrated MOF-5 (int-MOF-5) was synthesized using a mixture of size-matching linkers, and its gas adsorption performance was investigated. It was found that the addition of TZDC in the MIXMOF improved the uptake of H2 and CO2, providing a new approach for fine-tuning the confinement of small molecules.

Summary: This study prepared mixed metal metal-organic frameworks M-MOF-5 using the post-synthetic exchange technique and found that Ni-MOF-5 and Co-MOF-5 demonstrated higher hydrogen uptake capacities compared to the parent MOF-5. The Fe-MOF-5 exhibited decreased uptake due to the formation of discrete complexes with less crystalline nature. The Sips model was effective in describing the hydrogen adsorption isotherms in this study, with Ni- and Co-MOF-5 showing unique hydrogen uptakes, paving the way for further improvement in hydrogen uptake.

Summary: The study explores the application of photoswitches as light-responsive triggers for phase transitions of porous materials. By incorporating an azobenzene photoswitch in the backbone of a metal-organic framework, the researchers achieve light-induced structural contraction and gas adsorption control in the porous network. The complex mechanism of light-gated breathing is established, revealing a novel light-induced deformation mechanism of constrained azobenzene photoswitches.

Summary: A large library of novel porous salts based on charged coordination cages was synthesized through straightforward salt metathesis reactions, allowing for highly tunable metal identity, pore size, ligand functional groups, and surface area. The design principles outlined are expected to be widely applicable for the synthesis of new porous salts based on a variety of charged porous molecular precursors.

Summary: Understanding the mechanism of MOF crystal growth is crucial for their design. In this study, Deng and colleagues employ an optical method to visualize and track the crystal interface during MOF growth. They also derive a reaction kinetic equation for individual crystals of MOFs, which offers valuable guidance for MOF synthesis.

Summary: The fast development of Internet of Things and wearable electronics has created a demand for cost-effective and efficient electroactive materials for flexible energy storage devices. Binder-free nanostructured arrays have gained attention due to their ability to promote fast electron/ion transportation, withstand bending or twisting, and enhance the capacity of the whole device. The use of binder-free metal-organic framework (MOF) nanoarrays and MOF-derived nanoarrays with high surface area and unique porous structure has shown great potential in energy storage and has been extensively explored. This review compares and discusses the common substrates used for binder-free nanoarrays, analyzes the electrochemical performance of various MOF-based and MOF-derived nanoarrays, and examines their applications in flexible energy storage. The review also highlights key technical issues and future developments in this field.
